Battery Backup Guide

masterdeath01 asked:


Yup. That’s it. I have a watch and I want to see what kind of battery it uses. Is there any simple way I can open up the back plate SAFELY just to see what kind of battery it has? It’s obviously precious, so I don’t want to break it. I need to replace the cover back on afterwards.

Don’t be fresh. I need help. …well, it does have indentations. Except they’re REALLY itty-bitty small. I doubt a screwdriver will help me out. But thanks.

I’ve been looking at APC brand UPS (uniterruptable power supply) and need to figure out what the minimum size ups needed (700,1400, etc) to power the sump pump is…

Gardener_SA asked:


The battery is a 12V and the garage motor is 220V. Can I simply connect the battery to a 220Vinverter to convert dc to ac?

I just bought a 7 cubic foot chest freezer for our garage and I am about to stock it up. The freezer alarms that I have seen do not seem to be very loud. Nor do they give any back up in case the freezer goes out. My UPS battery backup that my PC is plugged in is VERY loud and I have about 15 minutes of warning. My question… can I plug my freezer into the same type of UPS that I use for my PC?
~thanks~

I would like to be able to open my garage door from the outside during a power failure, without extending the manual pull string to the outside of the garage. That means I need to add a battery backup of some sort to my Genie 3/4 hp unit. I’ve been researching online for hours and have drawn a zero. The uninterruptable power supplies I can find seem to be geared towards computers…200 watts or so. Is that enough to open once and close once (that’s all I need) without power? I think garage door openers take about 750 watts of power? The larger UPS backups cost more than a new opener with a battery backup already installed. Does anyone have any ideas ? Thank you!!

What’s the best sump pump backup that is availble and most reliable? I have heard negative reviews on battery backups and them failing. My partially finished basement recenly flooded due to a power outage which is why I am trying to pick one out.

Thanks!

I want to make solar powered fountain for my husband’s birthday. However, we do not get enough direct sun all day to power a “direct sunlight” solar panel. I would like to use a solar fountain pump and add a battery system to it so that the battery will charge and accomodate for periods of shade during the day. (Kind of like how solar garden lights power up all day and then run at night.)

I’ve seen systems and kits you can buy, but they seem ridiculously expensive and I’m sure this can’t be that difficult to do. Can anyone help me out w/ a How To?

I do have a basic understanding of electrical theory and wiring, but I am not an engineer, so please try to keep it simple. (I know about wiring, watts, volts, amps… I can install outlets, fix lights and understand balancing an electrical system to make sure the source is providing enough power and that the lamp won’t blow up, etc…. to give you an idea of where I am coming from.)

Thanks!

We live in a rural area.. we are looking at solar,wind,and battery backup and generators.. We really need enough to supply our house due to the harsh weather conditions here .The power doesnt fail often but I have a gut feeling we need the backup.We looked at generators that run about 3000 just for the generator but would like your ideas as to what would be a good investment or idea for backup.Any links to alternative power ideas that would supply 16 kw would be helpful or if you have ideas please let us know..Thanks for any info,also would like to mention im not physically able to build my own anything but maybe could hire someone locally if there were good enough plans for something.

My garage isn’t connected to the home….is there a type of garage door opener that has the manual override outside? Maybe with a key or wrench in case of power outage?? Or one with a battery backup?
